Hello & Welcome!!
The search function would be a good place to start for any new user, there is a lot of great content here for you to learn from others like yourself. I purchased a 2011 GT/CS a few short months ago and joined, and I learned a ton that way.
Best place to start is by figuring out what you want to do with the car. Daily driver, Auto-Cross, or Track? Then go from there... Welcome Aboard!
